一、安装jdk环境

1.下载jdk包

wget http://download.oracle.com/otn-pub/java/jdk/8u101-b13/jdk-8u101-linux-x64.rpm?AuthParam=1470128916_62d182598f9d06e4262730b9551516af ./

2.执行安装

rpm -ivh jdk-8u101-linux-x64.rpm

3.查看安装信息

# java -version

Java(TM) SE Runtime Environment (build 1.8.0_101-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

4.配置环境变量

vi /etc/profile

添加

JAVA_HOME=/usr/java/jdk1.8.0_101

JRE_HOME=/usr/java/jdk1.8.0_101/jre

PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib

export JAVA_HOME JRE_HOME PATH CLASSPATH

5.使环境变量生效

source /etc/profile

二、安装tomcat

1.下载tomcat包

wget http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.70/bin/apache-tomcat-7.0.70.tar.gz ./

3.拷贝到/usr/local目录下

cp apache-tomcat-7.0.70 /usr/local/tomcat -r

4.启动tomcat

# /usr/local/tomcat/bin/startup.sh

Using CATALINA_BASE:   /usr/local/tomcat

Using CATALINA_HOME:   /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp

Using JRE_HOME:        /usr/java/jdk1.8.0_101/jre

Tomcat started.

5.停止tomcat

/usr/local/tomcat/bin/shutdown.sh

6.永久开放8080端口

# firewall-cmd --add-port=8080/tcp --permanent
